SUZANNE MALVEAUX, CNN ANCHOR: Welcome back to AROUND THE WORLD. Here are some of the top stories we're following.

The Obama administration is now withholding some military aid to Egypt as it reviews how it wants to proceed. This follows a brutal crackdown against supporters of Egypt's first democratically elected president, Mohamed Morsy.

He was overthrown by the military last month and Washington is not yet calling it a coup.

IVAN WATSON, CNN ANCHOR: Egypt security forces may have upped the ante in their ongoing conflict with supporters of the Muslim Brotherhood. They arrested the group's spiritual leader today. He is 70-year-old Mohamed Badie.

State-run TV reports he's accused of inciting violence. He was found in an apartment in Cairo after being on the run since Egyptian security forces cleared the city's two main Islamist protest camps last week.

Badie's 38-year-old son, Ammar, was just killed in the violence.

Our own Nick Paton Walsh joins us from Cairo now. Nick, Mohamed Badie is the most senior leader in Egypt's Muslim Brotherhood. What's been the reaction there in Cairo to his arrest?

NICK PATON WALSH, CNN INTERNATIONAL CORRESPONDENT: A spokesman quite defiantly said that even though he's now in custody that doesn't dent the capacity to act of the millions of members of the Muslim Brotherhood.

And state media very quickly released details about this arrest, having shown pictures immediately afterward of him looking a little disheveled with an armed man next to him and a bulletproof vest, saying the 28-year-old teacher whose apartment he was hiding away in, worked at a school.

They raided the school, found there automatic rifles, a pistol and a bunch of equipment they say had been taken in a militant raid on a police station about 90 kilometers southeast of Cairo where I'm standing, effectively bolstering their narrative that they're dealing with terrorists here and Mr. Badie was hiding with someone with links to militancy.

But throughout the day, we've heard of further arrests. Fifty-six organizers across the country, overnight, arrested. Another middle level leader just in the previous few hours.

The Brotherhood, though, trying to look unfazed, appointing Mahmoud Essat, the deputy to Mr. Badie, as their new spiritual leader. He's known perhaps to be a little more hard line, but many are really asking right now, what are their options, Ivan?

WATSON: It's incredible. The party that was in power just a few weeks ago, now basically being called terrorists by the post-coup government there, Nick.

There's a big debate in the U.S. What should the U.S. be doing with its ally, Egypt, in this time of tension and conflict and killing?

What is the scene on the ground there? What are Egyptians saying about the U.S., which is supposed to be a close ally?

WALSH: The government has been quite harsh in its rebuke of U.S. criticism of its actions in the past week, but many people are really looking to see what are the actions going to be.

And we've seen this constant refrain from the European Union, the United Kingdom and the United States that, aside from the U.S. cancelling their military exercise next month, they are reviewing the nature of their aid to Egypt.

Now that was slightly bolstered today by suggestions of U.S. officials that they are, quote, "now reprogramming some of that aid," which seems to suggest that a tranche coming up in a few months may be delayed slightly. Congress is being notified of that.

But it's also a mechanism which allows them to switch it back on again in the future. And I'm sure, you know, the nature of the strategic relationship between Washington and Cairo, they need each other in many ways, perhaps the U.S. needing Egypt more regionally than Egypt needing the United States.

And I think many really see this as an attempt to try and show they're doing something while the spotlight is on the hideously brutal crackdown the past week, and then allow themselves freedom to perhaps go back to business as usual in a few weeks from now.

Ivan?

WATSON: Perhaps Washington is looking for some wiggle room with this very sticky situation.

Thanks, Nick.

MALVEAUX: And just ahead, he's the partner of the man who broke the NSA leaking story.

After being detained by the British government, he's now threatening to take legal action.

(COMMERCIAL BREAK)

WATSON: Welcome back to CNN's AROUND THE WORLD.

Now more fallout today from the British government's nine-hour detention of David Miranda. He's the partner of journalist Glenn Greenwald who broke the story about the existence of a security National Security Agency spying program.

MALVEAUX: Miranda, you see him on the right there, he's threatening legal action against the British government.

Now he says it was illegal for police to take him into custody in the first place. What they did, they seized his laptop, his phone, his USB memory sticks as well.

I want to bring in Matthew Chance who's following the story from London here. And tell us essentially what actually happened here. How did they discover him and why did they -- what was the explanation for holding him in the first place?

MATTHEW CHANCE, CNN CORRESPONDENT: The explanation was that he had been ferrying materials, suspected to be, obviously, documents from Edward Snowden from Rio de Janiero where he lives with Glenn Greenwald, that "Guardian" journalist that broke the story about the NSA links, to a filmmaker in Berlin who is presumably making some kind of documentary or feature film about the whole Snowden saga.

He was returning to Rio back through London when he was intercepted. Obviously the British authorities wanted to get their hands on those materials that he had in his position. That's why they took possession of his laptop, his mobile phone, a couple of memory sticks that he had in his possession as well as various other things as well.

And it was clearly quite an ordeal for David Miranda, this 28-year-old Brazilian partner of Glenn Greenwald. He said this. "They treated me like I was a criminal or someone about to attack the U.K. I was -- it was exhausting and frustrating, but I knew I wasn't doing anything wrong."

He also said that he was in a different country with different laws in a room with seven agents, coming and going, who kept asking me questions. I thought anything could happen.

So he was clearly quite spooked by this experience, and that's why he's started legal action to try and get the British to admit it was an illegal detention.

WATSON: And, Matthew, we're also getting reports from the British press that the British prime minister knew Miranda would be detained before this operation actually happened.

What do you know about that?

CHANCE: We've certainly had it confirmed that the British government knew that he was going to be detained before it happened.

The British home secretary, the sort of interior minister, Theresa May, has confirmed that she was told in advance that this detention was going to be made at Heathrow.

We also know from Downing Street and we've spoken to them, the British prime minister's office, of course, that they were kept abreast of this detention as it proceeded throughout these nine hours.

Also, interestingly, the White House was also kept abreast and given a tipoff as well that this had taken place, so the British and the Americans, apparently working hand in hand.

MALVEAUX: Matthew, in light of all that, all the folks who were tipped off on this, does he have a legal standing here?

CHANCE: It's -- very much remain to be seen, I'm afraid. His lawyers say that they're going to take this legal action possibly as early as tomorrow, possibly later in the week, to try and challenge this detention.

But the British authorities say that they did nothing wrong. Everything was legal and procedurally correct, so they're standing by the decision to detain him and question him in the way that they did.

MALVEAUX: All right, Matthew Chance, thank you so much.

And, of note here, Anderson Cooper is going to actually talk to both of them together and find out what their take is on all of this.

It's -- they both feel like they really have gone through a lot in terms of exposing this particular story.

WATSON: It should be a fascinating and potentially controversial interview.

And, of course, we're watching tickets for the World Cup going on sale today. Fans are ready, but organizers are concerned about whether or not Brazil is going to be ready.

We've got a live report, straight up ahead.

(COMMERCIAL BREAK)

WATSON: Welcome back.

This is the day that soccer fans, or football fans, if you will, AROUND THE WORLD have been waiting for. Tickets for the 2014 World Cup in Brazil went on sale today.

MALVEAUX: Are you a big fan?

WATSON: I like to watch. MALVEAUX: Listen to this. You can apply for tickets on the Web site for FIFA. That's the sport's international governing body.

And, of course, this is what we're talking about, if you're a real fan or not, the prices ranging from $90 for the first round matches to $990 for the finals.

More than 3.3 million fans attended the 2006 World Cup in Germany. Organizers expect that that many are going to be coming for the upcoming tournament as well, held June 12th through July 13th in Brazil.

WATSON: And that doesn't include, of course, air fare to Brazil.

MALVEAUX: You've got to be a real fan.

WATSON: Yeah, yeah. It's a big deal, of course, for much of the world, and Shasta Darlington is now joining us from Sao Paolo.

Shasta, can you explain how this first phase of ticket sales works?

SHASTA DARLINGTON, CNN INTERNATIONAL CORRESPONDENT: Absolutely, Ivan.

This is a three-stage process. And the first phase is actually the easiest, and that's because it's a lottery, so you don't have to rush online to make sure you get the tickets today. Anytime between now and October 10th you can go on FIFA's site, register and apply to buy the tickets. And you have just as good a shot if you do it today as if you do it on the 10th of October. After that, things speed up, get more competitive, and it really is a first come, first served kind of process.

But it's interesting, you guys were talking about the prices, the airfare, all of that is still just the tip of the iceberg. Even once you get here, these games are going to be held at 12 different stadiums in 12 different cities in a country that's bigger than the continental United States. So just to get from one game to the other, you're also going to spend a lot of money.

WATSON: Wow.

DARLINGTON: And, according to the tourism agency here, hotel prices are being jacked up to, in some cases, 500 times their normal price. So you better start saving, Ivan and Suzanne.

MALVEAUX: Oh, my God.

WATSON: Take out a loan.

MALVEAUX: Oh, my gosh. I mean I know some fans clearly of the World Cup. I don't know if they're going to be paying that much but, you know, maybe some people will. We've been talking a lot, Shasta, about some of the problems that Brazil has been having and whether or not they're ready. We're talking about security, all kinds of things that they have to deal with in a very short order. What have you seen from - you know, from venue to venue? Does it look like they're prepared for what they're about to be hit with?

DARLINGTON: You know, Suzanne, we just have to look at this on so many levels. When you talk about the stadiums, they will be ready. They may not be as sophisticated as initially planned. One stadium, for example, has decided not to put a roof over it because they just won't have it ready in time. The stadiums will be there.

I think what's really happening, though, is there's a lot of criticism because people this is just a lost opportunity for Brazil. Brazil has a lot of logistics problems. This is a country that OK recently surpassed the U.K. as the sixth largest economy, but it should have used this as an opportunity to really build out its infrastructure, and that's where the criticism is right now, Suzanne.

MALVEAUX: All right.

WATSON: Well, you know, there was some skepticism about South Africa. They hosted the last World Cup. But they managed to pull it off and it was a big success.

MALVEAUX: So you think CNN will sponsor us, pay for us to get over there?

WATSON: I'd love it. I'd love it.

MALVEAUX: All right, we'll see.

Just ahead on AROUND THE WORLD -

(BEGIN VIDEO CLIP)

UNIDENTIFIED FEMALE: And they always make fans laugh.

UNIDENTIFIED FEMALE: I know they love me even though they don't know me.

UNIDENTIFIED MALE: We are so thankful. This is the teamwork between us and them.

UNIDENTIFIED MALE: The fans were the ones who made up their minds.

(END VIDEO CLIP)

MALVEAUX: This boy band seems to have only one direction, and that is up. We are live from the London premier of their movie, up next.

(COMMERCIAL BREAK)

WATSON: Welcome back to CNN.

Happening right now in London, the world premiere of "One Direction," the movie. Now, if you have a teenager or know any, then you know that One Direction is the hottest boy band in the world. Fans lined up for hours to see this 3-D spectacular, which was directed by our own Morgan Spurlock. And I know this band is a huge favorite of yours, Suzanne. Well, our own Zain Verjee is there in London. She's in the middle of the madness.

I hear it's loud. Zain, what's going on over there?

ZAIN VERJEE, CNN CORRESPONDENT: OMG, Ivan. One D in 3-D. They've arrived here just moments ago and everyone behind me, 17,000 screaming fans, have gone totally nuts. Many of them have been here camping up for up to three days. They've got books out, papers just waiting for their autographs. The fans from around the world have one fear, Ivan, right now, and that is they're batteries will die from their smartphones. There's a little charging section there too.

Anyway, everyone is out here today to see the world premiere of "This Is Us." It's the movie about One Direction. Kind of what it's like behind the scenes. How difficult it is for their families to be away from them. What they're like with each. Do they argue? Do they get along? And just get a flavor of what that's like. So the movie's going to start in about an hour and the boys are hanging out signing loads of autographs and the movie's supposed to start pretty soon, actually. It don't know if they'll make it, Ivan. But the scene here in Leicester Square is total excitement, total chaos and loads of fun.

WATSON: And I can't even imagine what the reaction was like from the crowd when those - when those singers showed up on the scene. And is Morgan Spurlock, is he making an experience there on the red carpet?

VERJEE: The reaction was pretty amazing. And it sounded like ahh over and over again.

Morgan Spurlock is going to be here. This is an interesting choice for him to make. A popumentary like this. You know, he did "Super Size Me" (INAUDIBLE) on CNN with this documentary series as well. And what he said is that he really wanted to understand the kind of people mania behind these guys. But he said that it was an incredible experience and they're amazing guys. He's actually on his way down the red carpet. So we'll have a chat with him shortly.

But it's loads of fun here. Mass hysteria. Even the paramedics are on standby.

MALVEAUX: Yes, I need the paramedics to get through this - this segment. Obviously I'm not hip enough. I got - I got to get with the program, clearly.

WATSON: I -- this is not my specialty either, boy bands.

MALVEAUX: All right. We'll be - we'll be following Zain then.

WATSON: Absolutely. But sticking with the subject.

MALVEAUX: Sticking with the subject, all right. The last time we actually heard them sing "Bye-bye," it was more than a decade ago. You've got to check this out.

(BEGIN VIDEO CLIP)

'N SYNC (singing): Out that door, baby bye, bye, bye.

(END VIDEO CLIP)

MALVEAUX: All right, these guys, I know. "The New York Post" who are reporting beloved the '90s boy band 'N Sync is going to re-unit at the MT Video Music Awards this weekend. J.T., Justin Timberlake, is going to reportedly take the stage with his former band mates on the Sunday show. If it happens, it's going to one of the group's first performances together since they broke up back in 2002. I like these guys.

WATSON: We were all a little boy crazy then.

MALVEAUX: Yes. All right, just ahead on AROUND THE WORLD, this is even better. It's a bird, a plane. No, it's our own Richard Quest. We'll explain.

(COMMERCIAL BREAK)

MALVEAUX: Richard Quest, our go to reporter when it comes to planes and aviation, right? Well, now, the latest craze, he actually flies himself without a plane.

WATSON: That's right. Well, it turns out celebrities like Rob Lowe and Leonardo DiCaprio were doing it, so it's only natural that Richard would want to try to fly strapped to a water jet pack.

MALVEAUX: All right, so let's just watch -- take a minute to watch what happens here. Oh - oh, we saw a bit of a crash here. But before it looked like - it looked like a lot of fun. Richard's with us here.

Richard, tell us what on earth are you doing here? What is this?

RICHARD QUEST, CNN CORRESPONDENT: Trying to stay in the air. It is, by far and away, the most fun I've had. I mean basically -- oh, yes, that was painful. Basically you -- they control the water - the speed of the water on the ground, on the shore, because otherwise it's too powerful. And it is the closest you'll ever get to flying because you literally are using your hands. It's literally flying. Your -- the water's shooting out the back of the jetpack. You're steering yourself left and right. And if it all goes wrong, you go straight down into the water.

MALVEAUX: How does it go wrong? Wait, how do you explain that, because you've got two different controls there, right?

QUEST: Because if you pull the kill pin, or you go head over heels, you will fall. The power stops.

What is interesting about this the way in which - it's about a $70,000 to $100,000 piece of equipment. I did it on The River Thames.

WATSON: Freezing.

QUEST: It was a nice day, but it was chilly.

WATSON: OK. Right.

QUEST: Chilly is the way I would describe -

WATSON: It's not known for its warm water.

QUEST: No. No. And certain places like Hawaii, Honolulu, are looking at this with great concern because it's such a fast growing enterprise, they say it could ruin the reef, all that churning up of the water, the water craft users hate the fact they get splashed because you're all 1,000 gallons a minute coming straight out of the back of these two hoses. And also, don't forget, if you fall into the reef, you'll hurt yourself.

MALVEAUX: Yes.

WATSON: Is that -- is that hose connected to anything?

QUEST: Yes. It basically - sorry, to those who are uninitiated, the jetpack has a hose. The hose is connected to an unmanned water craft on the water which churns up the water, sends it up the hose, and you're sort of on the top and you're sort of steering yourself like that.

MALVEAUX: Come back, Richard, come back.

QUEST: And it really is an enormous amount of fun because you just literally steer yourself around. And then you pull it and puh (ph).

WATSON: Did you go under the London Bridge?

QUEST: Don't be ridiculous. London Bridge.

MALVEAUX: No, but you're a thrill seeker, right? So how does this compare to the other things you did, like when you like got out of -

QUEST: It is by far and away better than water skiing, jet skiing. I loved it. I - it was - but it's so expensive. It's about $200 an hour. This is expensive compared to all the other ones. But I loved it.

MALVEAUX: All right, a 15-minute version. I'll do it. Yes, there you go. There you go. We like it.

QUEST: (INAUDIBLE).

WATSON: Thanks, Richard. Wow. One day.

MALVEAUX: (INAUDIBLE). Yes.

WATSON: Let's see you in one of those things, huh?

MALVEAUX: Hey, you know, I'll do it for 15 minutes.

QUEST: Will somebody sponsor her to do it?

MALVEAUX: (INAUDIBLE).

All right, they're telling us we've got to go. We'll see you in a little bit.
